How Do Coastal And Interior Plains Differ?

How Do Coastal And Interior Plains Differ
The appropriate answer is “The position of coastal and interior plains differs, since coastal plains are next to the sea while interior plains are in the centre of the region. Coastal and interior plains share the characteristics of being structurally flat and low-lying “.

What is the distinction between an inner plain and a coastal plain?

The approximately 500-mile-long Gulf Coastal Plain in North America is an example of a coastal plain. Over the course of millions of years, sediments from mountains are deposited on inland waters, forming rock layers upon layers. This is referred to as an internal plain. The Interior Plains of North America are one example.

The Coastal Plains ecoregion encompasses the whole state of Florida, the eastern portion of Texas, and the Atlantic shoreline from Florida to New Jersey. It encompasses the Mississippi Delta and Gulf Coast and stretches north along the Mississippi River to the junction of the Mississippi and Ohio rivers.

  1. The overall geographical area of this ecoregion is approximately 395 000 square miles, or 13 percent of the contiguous United States.7 percent of this region, or 25,890 square miles, is federally owned.
  2. The Mississippi, Suwannee, Savannah, Potomac, Delaware, Susquehanna, James, Sabine, Brazos, and Guadalupe are among the river systems within the Coastal Plains ecoregion or crossing it.

The river environments of the Coastal Plains ecoregion include the largest number of indigenous aquatic organism species in North America. These creatures include of fish, aquatic invertebrates, and mollusks, in addition to peculiar species like paddlefish, American alligators, and huge aquatic salamanders.

An estimated 18% of aquatic species in this ecoregion are considered vulnerable or endangered. Historically, this ecoregion included large bottomlands that were flooded for many months each year; today, these regions are heavily channelized and limited by levees. Riparian ecosystems and native aquatic wildlife have been impacted by acid mine drainage, urban runoff, air pollution, sedimentation, and the introduction of invasive (non-native) species.

In general, rivers in the Coastal Plains construct complex wetland topographies with natural levees, back swamps, and oxbow lakes over flat plains caused by river deposits. Typically, they drain thickly vegetated watersheds; well-developed soils, moderate rainfall, and subsurface fluxes maintain relatively low suspended sediment levels in rivers.

  1. A notable exception is the Mississippi River, which transports substantial sediment loads from dry regions in the drainage basin’s center and western portions.
  2. The overall river and stream length in the Coastal Plains ecoregion represented in NRSA 2013–14 is 198,824 miles.
  3. This ecoregion consists primarily of flat plains, barrier islands, several wetland areas, and around 50 significant estuary systems along its coastal edges.

The climate is moderate to subtropical, with average annual temperatures between 50 and 80 degrees Fahrenheit and yearly precipitation between 30 and 79 inches.

What differentiates Class 6 western coastal lowlands from eastern coastal plains?

The Eastern Coastal Plains are a vast expanse of land between the Bay of Bengal and the Eastern Ghats. Complete response: The Western and Eastern Coastal Plains are essential physical features of India, yet their geographical characteristics are considerably distinct. Some distinctions are:

S. No. Western Coastal Plains Eastern Coastal Plains
1. The Western Coastal Plains are a huge stretch of landmass between the Western Ghats and the Arabian Sea for a length of 50Km. The Eastern Coastal Plains are also a huge stretch of landmass but are located between the Eastern Ghats and the Bay of Bengal. This stretch of land is more levelled and is wider than the Western Coastal Plains.
2. The region consists of three sections – The Northern part of the coast from Maharashtra and Goa is called the Konkan Coast. The central stretch in the state of Karnataka called the Karavali Coast and the southern stretch which is in the state of Kerala is called the Malabar Coast. The northern part of this plain region is called the Northern Circars and the southern part is known as the Coromandel Coast. These plains stretch from Tamil Nadu in the south to West Bengal in the north and go through Andhra Pradesh and Odisha.
3. On the Northern side of the Western Coastal Plains, which is the Konkan region, there are two gulfs called the Gulf of Khambhat and the Gulf of Kutch. Deltas of India’s major rivers form a huge portion of these plains. The Mahanadi, Godavari, Kaveri, and Krishna are the rivers that drain in these plains. Along with the deltas, the Chilka Lake, a brackish water lake along the eastern coastal plain is also an important part of the Eastern Coastal Plains.

Note: This notion should not be confused with the Western and Eastern Ghats. The Western Ghats are a parallel mountain range on the west coast of India. The Eastern Ghats are a mountain range along the eastern coast of our nation.
